spools, the adjoining yarns from adjoining spools will lead off from the spools more widely spaced than the tubes.

The projecting ends of the tubes rest on a rubber cushion 30 which covers the upper fiangeof a channel beam 31 which is a part of the framework of the machine,

g A clamping bracket 32'overlies theen'ds of the tubes and is pressed down on them by drawingforward either of thehand leverst33, 33 on a rock shaft '34.

" links 35, 35. The underside of the bracket carries serrations 36,736 which enter between the'tubes ofthe tube-frame in order that a 'tightjoint may be effected and p'as sage of air outside the tubes prevented, I p p g On the uppergside'of the'bra'cket are chane ls for positioning and supporting temporeachicngaging all of the yarn ends on aspool,

ary holders 37, 37for the yarn ends. These holders are applied at the time of spooling,

and they are brought to the machine with the "spools and tube-frame. When set in place on'thebracket a uniformly spaced group of parallel yarns is vdrawn between 'each spool and the temporary holder for the yarn ends and theadjacent yarns of adjacent spools are 1 more widelyisp'aced. Three bars '38, 39, 40

when lowered the yarns of one of the spools" j V 1 are carried above the yarns drawn between the spools an'd'thetemporary holders. Each bar hasserrations on its underside to receive when the yarns are drawn betweenthe spool and its temporary holder and the serrations rest againstthe topof the main cross bar of the tube-frame and thereby form a series of guide'tubes for the yarns. These bars are.

carried by a beam 41 which has arms 42, 42 at its ends carried on' shafts 43. 43 journalled in the endframes 44. 44 of the machine, so asto permit of the raising and lowering'of the beam with the serrated bars. 7

" The bars at:either end can he slid longitu- 'dinally' along the beam and canbe spaced from the middle bar topositions where their serrations can engage the yarns of the end spools, or the ends of the bars can be brought together toform a uniformly spacedseries" of guidetubes opposite the tubes of the tubeframe'. "The beam is lifted through arms 45,

45 through connecting rods 46, 46 and cams 47 ,47 and is supported through these parts in space betweenthe guide tubes and .thetubes of the tube-frame andthereby connect them. I As this gate plate is lowered relative to I the beam whichcarries it, the end bars of the threeba'rs forming the guide tubes are moved V. -longitudinally so that their ends abut the ends, of-the c'f middle ba r. -Tl1is 1 is effected Connection to the bracket dis through:

opposite sides of the beam.

The flanges at the outer ends of the end I spools are engaged by rubber faced friction wheels 54, 54 which are pressed toward each other by cams 55, 55. The cams are turned throughlinks 57, 57 and arms 58, 58 with through bell-cranks each with arms 52, 53 on I "by handles 56, 56 which may be'connected the rock shaft throughwhich the tubes of the'tube-frame are clamped sothat all may be clamped through one handle. The spools are coupled'together so that the middle spool turns with the end spools. through these friction wheels have both hand and power adjustment The shafts The spools which carry these friction wh'eelshave gears 1 59,159 connected through :an intermediate gear 60. A lever 61 carries alatch 62 which connects the lever and gear. 'The lever is operated through a connecting rod63 from cams 64, 65. For hand operation, a handwheel 66is. loosely carried on a shaft. At-

tached to its hub is a gearj67 for the operation of the friction wheels when shifted axially to bringthe gears into mesh. Such shifting jalso unl-atches the power connectlODQ Theconnection is to a larger gear 68,

thereby affording mechanical advantage and "rendering it easier to make the properadjustment, r

Air isexhausted from a vacuum chamber Q70 through a screen 7l,'valve 72 and pipe 73.

The valve is controlled through an arm 74,

connecting rod 7 5'andcamjs 76, 77. To provide additional capacityto the vacuum chamber, adrum 78 is coupled thereto. 'The' vacuum chamber has a slot opposite'the line ofv which is closed by a tubes of the tube-frame bar 79 which is a slot valve carried by vertically guided bars 80, 80 which are operated throughconnecting rods, 81, 81 from cams 82 83. 1" i 0 i4 shaft 85 carries the cams: wIt is driven 'throughgears'86, 87- from a jack shaft88.

The jack shaft carries a loose pulley-89 which connects with the shaft through clutch 90. The clutch is applied by aspringarm 92' of a bell-crank at'ed'fro'm a shaft :arm shaft which bears on lever which is; oper- 93 carried the cam the other arm 94 of th'e bell-crank lever when: the shaft has made 'mevmuaon and reaches its initialfposition.

To insure return of the bell-crank arm intothe path of the shaft arm so that the; cam shaft will ;-'be stopped 11 when it has fi ade' a revolution, an arm '97 is providedon "the bell-.crank lever, and is engaged-by the r f fil -cfenls le er t its; pemeve posltlonf 1 7 7 7 I P 5 I1; operating the 11sech ir e and whileit lis at rest and the 411s upreised, the tube-- frame with its speols filled with yarn is set ih place. 7 The tube frame usually has slight cjainberf and: to) make it straight itis engagect by 21 lzitehfQS; gpetatedthr'eugh a hand; lever 9 9 The tube enpls are set a between the rubb e eushioh' 30,- tvihich is un der them); and the clamping bl atiket 32 which everlies them and'is serratedpso as t0 7 the slot that-sir CaDQOt-PQJSSGXCQPt through tieh whe els aI eplai ed on the flanges at the outer ends ot the end spools.
